Derating Curves
1. Convection-cooled, output power must not exceed 120 W for
combined V1, V2, & V3
2. For 5 V standby (V3), Power OK & Inhibit, add suffix ‘-A’ to model number.
3. For covered versions, add suffix ‘-C’ to model number or order part no.
ECM140 COVER KIT for standalone cover (see derating curves).
Not suitable for use in class II installations.
Notes
1. 10 CFM airflow achieved with system cooling or with Top Fan assembly.
2. For 5 V standby (V3), Power OK & Inhibit, add suffix ‘-A’ to model number e.g.
ECM140US12-A.
3. For cover with Top Fan assembly please refer to longform datasheet for
mechanical details.
